"Shh.....h Be quiet, it's a pre-show show, and we need some quiet to get everyone in the mood....."

In the small room, the woman's eyes widened and she looked at the man in front of her in horror, tears of fear slowly flowing down the corners of her eyes. The man, on the other hand, turned a blind eye to all of this and still looked at the woman in front of him with a smile.

A huge bolt of lightning streaked across the night sky, illuminating the dark room. The final mirror image that catches the woman's eye is the man with clown makeup spraying her with a sprayer.......

"Head! It's been sampled."

The general police officer saw Gordon coming and immediately reported the current progress of the situation, Gordon nodded to indicate that he heard it, and then the little policeman went to continue his work of sweeping the tail.

Gordon glanced at the room, it was very ordinary, one room, one bathroom, one bathroom and one bathroom, this is a typical apartment house specially used for rent, it is a bit old, but it is also different from those houses that are almost dilapidated in the old city.

The house has been carefully maintained from the early days of construction to the present, and it occupies a good lot, and it has never been worried about renting.

The current tenant of the room is an office worker woman who works as an assistant in Lane's chemistry lab and is single. It's pretty ordinary, at least that's what the information says. The cause of death was due to suffocation due to an overdose of laughing gas.

The person who found the body was the manager of the apartment, and he came because the tenant was supposed to pay the rent two weeks ago, but it had been delayed for two weeks.

The tenant was a long-term tenant here, had never defaulted on rent, and the manager agreed to postpone the collection of rent because he worked for a very profitable company, but it dragged on for two weeks.

Today is the normal rest time for tenants on weekends, so he came early in the morning to collect the rent, but no one came to open the door after knocking on the door many times in a row, and he twisted the doorknob in a very bad mood but found that the door was not locked, and immediately called the police when he saw the woman lying on the ground as soon as he entered the room.

"Well, in other words, this woman is likely to be laughing in her room and not laughing to death?"

Gordon scratched his bald head and said indifferently, he couldn't understand why these young people would find a way to get "drugs" and "drug-like" things to make themselves empty for a long time.

According to the information, the woman's age is only 22 years old, and she is in the prime of her life. She also has a promising job, and the people in the laboratory have a good evaluation of her, rarely go to nightclubs, and go to the library when she has time. I feel that he should be a good young man who is striving for progress. As for why she inhaled laughing gas, none of the people who knew her could say it, and some of them couldn't even believe that she could inhale laughing gas.

"Well, the interpersonal relationship is also very simple, maybe it was an accident, what about the corpse?"

Although it is a pity, but this kind of thing is also very normal, a good student who has been obedient all the year round, after suffering from pressure or being lured by a bad friend to come into contact with drugs or drugs, this is also within the normal range.

"What about the corpses?"

"An autopsy is underway, and after the autopsy confirms the cause of death, it can be handed over to her relatives."

The little cop answered Gordon's question.

"Relatives? Won't her parents come? ”

"Her parents seem to have divorced very early, and she was brought up by her aunt"

"Oh"

Gordon casually crouched on the ground near the traces of the drawing, casually examining them and casually asking small questions.

The room is very small and you can see the head at a glance, the administrator is very responsible to protect the scene as much as possible, the room is very messy and the windows are wide open, but I don't know if this is a masterpiece after she inhaled laughing gas or other reasons.

The site was quickly surveyed, and before leaving, the caretaker asked when the house could be rented out again. Renting a house in such a bustling central area for one day less is a loss.

"Hmm... Wait for the results to come out, if it is defined as an accident, you can rent again"

After giving the manager an incomprehensible answer, he returned to the police station, he originally thought that this matter had nothing to do with him, after all, there were too many such accidents. However, a message from the autopsy report shattered all his thoughts.

When the autopsy report came out, it was already night, and Gordon, who worked overtime as a regular occurrence, decided to read the report again and go home. However, when he saw traces of restraint on his wrists and upper arms during the trauma examination of the corpse, he knew that it was not a simple accident.

The residue in the sprayer that was left behind from the scene was detected as a high concentration of laughing gas. A guy who can kill people with laughing gas, Gordon can only think of that green-haired madman in Gotham if he wants to break his head. So he changed his mind and went to the roof of the building where the bat lantern was, and turned on the light.

Soon a dark shadow landed on the rooftop, and Gordon saw him and handed over the information in his hand. Batman took the information and carefully examined it for a while, then asked:

"Is the scene still there?"

"Ah, it's still there, I'll let the administrator leave it as it is until the police report comes out"

“... I got it, I'll check it out."

The work has been done, but Gordon hasn't seen the imp next to Batman for a few days, he is a little worried, after all, there are lessons from the past, even after so many years, Batman's attitude towards the Joker has changed, he can see it clearly, scratched his head and moved his gaze to the other side and pretended not to care and asked:

“... That one.. Why haven't you seen Robin in a while??"

Gordon didn't answer anything after asking, and the man who had already had a hunch turned his head, and sure enough, there was no one behind him, and this man never knew how to say hello before leaving.

“..... Sooner or later, I'll have to learn this trick too."

Gordon muttered and left the roof.

Batman arrives at the victim's rented house, which remains as it is at the request of the police.

After turning on the search function of the goggles, I entered the room and searched carefully.

The messy footsteps on the ground can be judged by the distance from the corpse to which are the soles of the police's shoes. Under the high-tech scanning, things that are not visible to the naked eye quickly become apparent, such as a little dirty mark on the leg of the toppled chair. Walk over and carefully remove this part and put it in a sealed bag to prepare to go back for testing.

Most of the stuff here has been taken by the police, and all the evidence known to the police, Gordon has also handed over to him.

After making sure that there were no other valuable clues in the room, Batman left the area and returned to the Batcave to begin his investigation.

The test results came out quickly, the main component of the chair's legs was iron, this mark was the result of corrosion by chemicals, the time is still quite new, and the composition of chemicals can still be found in it.

Bruce already had a rough guess about the content of the ingredients, and sure enough, the ingredients were exactly the same as those used by the Joker.

"Master Bruce?"

When Alfred came over with cookies, he watched Bruce look at the results with a gaze that was eager to open two holes in the screen.

"You're finally out"

The last time the Joker ran away from him and Jason, he hadn't been able to find the slightest clue after looking for him, and this guy finally ran out impatiently.

And more than the Joker himself, Bruce knew Jason was going to do something...... He sure will!
